In vitro experiments on fresh blood of eighty presumably healthy people point to a possible existence in the erythrocytes of gas cavities. This conclusion is supported by the following observations: 1) the ESR increases irreversibly during or after blood compression up to (220) atm; 2) the ESR increases reversibly under blood decompression up to 0.8 atm; the ESR returns to the norm when the pressure recovers to the norm; 3) the principal planes of section of normal erythrocyte sedimentation are oriented primarily horizontally, whereas under compression or decompression these planes are oriented primarily vertically; 4) the density of blood increases after or during compression, whereas laky blood does not change its density under compression. Recent acoustic and hydrodynamic experiments confirming possible existence of gas cavities in erythrocytes are described.
